Request to add details for mocking metastore variables

[prestonlewis]

Hi team, the request is to add best practice(s) around mocking metastore variables for use in unit tests. I've been able to pull together the following code in my code but curious if you have other/better approaches for mocking out Variables for use in pytest or other unit test frameworks. Thanks.

from airflow.models.variable import Variable

def test_dummy(monkeypatch):
  def mock_get(*args, **kwargs):
    mocked_dict = { "dummy_key1":"dummy_val1","dummy_key2":"dummy_val2"}  
    return mocked_dict.get(args[0])

  monkeypatch.setattr(Variable,"get",mock_get)

  dummy_var = Variable.get("dummy_key1")
